There are 1.51x10^24 atomsU in 2.50 mol of Uranium.

This is because a mole consists of 6.02x10^24 atoms. SO with this info,
2.5 x 6.02 x 10 = 1.505 x 10^24
but because we must round, the answer is 1.51 x 10^24

*mic drop*
XD silliness aside, I hope this helped!

Answer:

Number of atoms = [tex]2.5X6.023X10^{23}=1.51X10^{24}[/tex]

Explanation:

In each mole of any substance there are Avagadro's number of molecule or atom.

Avagadro's number = [tex]6.023X10^{23}[/tex]

The number of moles of uranium given = 2.5 mol

The number of atoms in 2.5 moles of uranium will be

Number of atoms = [tex]2.5X6.023X10^{23}=1.51X10^{24}[/tex]
